Since I don't make any changes to org-mode codebase and the only thing that has to be changed everytime Makefile changes is the path info, this is a bit faster than editing the Makefile everytime.

Though it took me sometime to figure it out and there's still this nagging doubt whether there's a even simpler way.

Any ideas?

EDIT: Just realised that the patch file will have to edited to have ONLY the changes you want else it will remove the newer lines added to other parts of the Makefile. So, this post is kind of wrong and displays a slightly addled view of patching AND version control.
